I have a little red bellied male in my yard who is quite tame. It appears he lost his tail feathers. I asked on another forum and posted a pic, and they said he is an adult, just lost a tail. Is there anything I can do in my backyard to help him survive? He seems to know all the ways of an adult bird (caches food), hops around, eats food from ground, will eat things I give him. He comes and goes most independently, except he can't fly. I freak out every day I don't see him and worry he's too tame. I live in NY (Downstate) so we get quite miserably weather in winter, usually not brutal (but can get bad) and moderate snow. Will this tail grow back? I have a lot of other birds, including another male who now hangs around for the seeds and peanut suet I put out. I don't want him beating up my little friend. Any advice is welcome.
